Parties that manage fisheries with identified marine mammal bycatch problems are urged to take account of the Hamilton and Baker (2019) assessment, available as UNEP/CMS/COP13/Inf.11 and, once available, the Food and Agriculture Organization of the United Nations (FAO) Technical Guidelines to reduce bycatch of marine mammals in capture fisheries and the Leaper and Calderan (2018) study of methods used to reduce risks of cetacean bycatch and entanglements (CMS Technical Series Publication No. 38), in addition to the best available scientific advice for the fisheries concerned and implement effective bycatch mitigation measures for marine mammals, as appropriate to their fishing operations including the introduction of alternative gears.
